OPERATION

General

Feed from the positive battery terminal (C0192) is supplied to fusible link 3, fusible link 9 and fusible link 12 of the engine compartment fuse box (C0632) on an R wire. Fusible link 12 (C0570) provides a constant battery feed to the lighting switch (C0041) on a UN wire. A second constant battery feed is provided by fusible link 12 (C0575) to the lighting switch (C0041) on an RN wire.

Fusible link 9 (C0570) provides a constant battery feed to the headlamp main/dipped beam relay (C0587) on an N wire. The headlamp main/dipped beam relay is located in the passenger compartment fuse box.

Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the ignition switch is turned to the 'ignition' position, current flows across the switch (C0028) to fuse 8 of the passenger compartment fuse box (C0588) on a G wire. Fuse 8 provides an ignition feed to the Central Control Unit (CCU) (C0593), which is mounted directly onto the rear of the passenger compartment fuse box.

Side Lamps

When the lighting switch is turned to the side lamp position, current flows across the switch (C0041) to fuse 16 and fuse 28 of the passenger compartment fuse box (C0587) on an R wire. Fuse 16 (C0582) provides a feed to the following on RO wires:

The RH side lamp (C0011). The RH front side marker lamp (C0916) (NAS vehicles only).

Fuse 16 (C0583) also provides a feed to the following on RO wires:

The RH tail lamp (C0125). The RH rear side marker lamp (C0918) (NAS vehicles only). The rear number plate lamp (C0138). The trailer pick-up (C0499).

All are earthed on B wires except the trailer pick-up, which is earthed on a W then B wire.

Fuse 28 (C0581) provides a feed to the following on RB wires:

The LH side lamp (C0009). The LH front side marker lamp (C0917) (NAS vehicles only).

Fuse 28 (C0583) also provides a feed to the following on RB wires:

The LH tail lamp (C0121). The LH rear side marker lamp (C0919) (NAS vehicles only). The trailer pick-up (C0499).

All are earthed on B wires except the trailer pick-up, which is earthed on a W then B wire.
